Not all buildings that end up on Historic England's 'at risk' list have a happy ending, but that is not true for World War I hangers on the Wirral peninsula.
The former RAF base at Hooton Park has undergone years of restoration work to bring them into use and protect an important slice of aviation history.
And included in its long and important past is the story of how it became Liverpool's first airport.
The site was originally a racecourse but became an aerodrome in 1917 and was used as a site to train the army and pilots.
In 1930, 11 years after the Royal Flying Corps disbanded from the area in 1919, Hooton officially became Liverpool Airport serving the Northwest.
A title the Hooton site held for three years before Speke - now known as Liverpool John Lennon Airport - took it when it was officially named in July 1933.
When World War II hit, Hooton became an industrial hub of activity housing bombers such as Fairey Battles, Hurricanes and Spitfires.
Patrol flights operated out of Hooton across the Irish Sea and RAF aircraft were assembled and repaired. One of its most poignant moments during WWII was during the retreat from Dunkirk - the evacuation of Allied soldiers from the beaches of Dunkirk in 1940 - when a huge variety of aircraft landed at Hooton.
While aircraft repair work continued at the site after the war, it closed in 1957 and was later bought by Vauxhall Motors in 1962.
Hooton Park slowly fell into disrepair, and with the risk of losing the historic site, The Hooton Park Trust was founded in 2000.
After taking ownership of the extensive site, the trust looked to preserve the Hangers for future generations.
Due to the conditions of the buildings, they were put on Historic England's 'at risk' list in 2003.
In 2018, Building 17 (Central) and Building 18 (Southern) GS sheds were taken off the register thanks to repairs funded by Historic England, WREN (landfill tax), Vauxhall matching funding and the dedicated team of the Hooton Park Trust.
These two sites have become venues of heritage open days and the trust supports restoration work by storing people's cars for a fee.
That left Building 16, which remains on the list and the chairman of the Hooton Park Trust, Graham Sparkes said it isn't quite ready to come off just yet, but the end is in sight.
Mr Sparkes said: "Building 16 was considered to be beyond repair the south bay roof having collapsed in December 2011 and the north bay roof being held in place by scaffold bracing along its centre line.
"The truss (Belfast roof truss) roots on each side in the main collapsed. A grant of £350,000.00 was secured via the LIBOR fines from the then chancellor George Osbourne.
"The Trust then decided that this was enough to get the resurrection of the building started. Thirty-four new 80-foot span timber trusses were constructed on-site and lifted into position before the money ran out.
"Further funding was found and the new roof and building ends were constructed. The work to this point was outside the funding parameters of Historic England as we were new build as opposed to repairing existing.
"The remaining works were to the original parts of the building and so we began talks with Historic England for funding the completion of the restoration.
"Then Covid happened. Funding dried up and we have been left to our own resources which has slowed progress as we are now earning what we spend.
"The Trust has replaced the two annex roofs and we currently have contractors in to refurbish the 28 high-level windows which will complete the weatherproofing of the building.
"Further fundraising and works such as render repairs, electrical installations and setting the building up for its intended role as the focus of our community program and an interactive museum display looks to keep us busy for the next couple of years.
"So, in conclusion, we are not quite ready to request removal from the at risk register of Building 16 but we are working to that end and it is our belief that once we are again able to open our doors to visitors we can grow our volunteer base and move forwards."
